Can anyone shed some light or share some experiences? Calamity, there are versions of Atom 15 that post-date the issues with modifying the bios, so i presume that part would work. But there's nothing confirmed for flashing the BIOS back and getting it working.
Hi buttersoft,
Not sure if I understand your question, but the R9 380 should not be different from other cards with regards to ATOM-15 flashing. It's true that the most complex a card is (the more outputs it has), the most difficult to figure out how outputs are going to behave after flashing it. I experienced this with my R9 270, I thought it was bricked and it turned out it was working fine once I used the proper output, I can't remember the details. It's more of a matter of bypassing the issues with suddendly blanked-out monitors that are often too much for a novice.
With regards to patching the bios itself, unfortunately newer bios revisions have less blank space to work with. And although ATOM-15 is now capable of really daring stuff like relocating the uefi bios part in order to get more room, this is not always the solution, specifically if the legacy bios part is too big. The patch still requires 532 bytes of free space, and sometimes it just doesn't exist.
